Back 20 years ago there's a product in the summit magazine that was a negative ionizer for fuel.They tested it on a 700 horsepower big block Chevy and got 20 more horsepower out of the engine. It used about 50 watts of power and put a negative charge on the fuel going into the carburetor.I know a guy with that device on 70 Charger and knocked off .15 in the quarter mile.
